Abstract
PURPOSE: To prepare a highly stereoregular polyolefin without the ash-removing process, by using a catalyst system comprising an organoaluminum compound and a component provided by contacting a magnesium compound with an unsaturated ether compound, etc. and thereafter treating the product with a titanium compound and an ether compound.
CONSTITUTION: An olefin (e.g. ethylene) is polymerized in the presence of a catalyst system comprising (A) a particulate solid provided by mechanically contacting (a) a magnesium dihalide (e.g. magnesium chloride) with (b) an ether compound having an unsaturated group (e.g. allyl ethers) and if necessary (c) a silicon compound I (X is halogen; R is 1W10C alkyl; n is integer of 0W4), and thereafter treating the product with a mixture of (d) a titanium compound (e.g. titanium tetrahalide) and (e) an ether compound II (RI is 1W10C alkyl; RII is alkyl or ether bond-containing group), and (B) an organoaluminum compound.
